I've got an idea whereby people linking to a new site will get something for free on a recurring basis. I therefore need to make sure that the links are up all the time and not just when they know I will check them / when the freebee comes.
How do I monitor that those website link to me if the number of sites become unmanageable - over a 200/300 or so?
I thought of designing a piece of software working a bit like an SE spider - on one end I feed the URL's that it should spider to see if the link to my site is there - on the other it lists the code for the site that do (to check anchor text etc...) and the sites that don't have the link anymore.
The only problem is ... I have NO CLUE on how to do that.
